| Outline of Final Research Achievements |
This study explored the potential development of social choice theory in the framework of information study. In particular, it focused on Amartya Sen’s theory and proposed a software system to calculate the amount of information processing needed in a social choice procedure to examine the validity of the theory. In the software system, a Shannon-based calculation method was introduced to evaluate the amount of information. Sen’s framework has a characteristic in that it contains logics for social choices, which are not based on simple voting but on observation and evaluation from the viewpoint of society. This aspect is now related to various approaches to establish “happiness” indexes, although Sen himself did not intend this originally. The quantitative analysis method developed by this study is expected to serve as a tool to re-examine the degree of how a desirable social choice is achievable via an observation- and evaluation-based methodology.
